[snappyHexMesh] OpenFoam problem with generation mesh

stempellek · June 23, 2019, 16:51

Hello,
I am new in OpenFoam. I have to generate a mesh on blood vessels model in the brain. I readed that I can do it using blockMesh and then snappyHexMesh. My model has 3 inlet and 10 outlet. For start I divided model for 4 blocks (for easy understand). I readed also that the snappyHexMesh will work only on the block the locationInMesh is in. So I wanted to generated four difrent mesh and then connecting it (if it can ?). But when I set locationInMesh for first block I get a lot of mistakes using snappyHexMesh and I don't know how to solve it....Could someone help me ?

Hello Anna,

It's going to be hard to help you without knowing exactly what kind of problems you're facing.
You should at least post your snappyHexMeshDict file and a log file showing the errors you get when you try to execute snappyHexMesh.

See how to give enough information to get help.
